Haihao Group is your trusted partner for GOST 33259 Gr.F22 Cl.3 RTJ weld neck flanges

In the demanding world of industrial equipment and components, finding a reliable supplier who can deliver top-notch products tailored to your exact specifications is crucial. Haihao Group is proud to announce that we have recently fulfilled an order for GOST 33259 Gr.F22 Cl.3 RTJ weld neck flanges for our esteemed Russian client, showcasing our commitment to excellence and customization.

Meeting Stringent Standards and Specifications

Our Russian client required RTJ weld neck flanges adhering to the GOST 33259 standard, specifically in Gr.F22 Cl.3 material. The ordered sizes included DN250 with a PN100 rating, ensuring compatibility with their existing systems and applications. Understanding the critical nature of these components, we took every step necessary to meet and exceed their expectations.

Comprehensive Manufacturing and Testing Processes

We subjected the RTJ weld neck flanges to rigorous heat treatment processes, ensuring optimal material properties and long-term durability. Furthermore, each flange underwent a 100% UT (Ultrasonic Testing) inspection to detect any internal defects, guaranteeing flawless construction.

To meet the specific requirements of our client, we conducted KCV (Charpy V-notch) impact toughness tests at minus 20°C. The test results showed impact energy values not less than 50 J/cm², demonstrating the exceptional resilience and strength of our products under extreme conditions. Additionally, the hardness of the flanges was verified to be no less than 174HB, ensuring they could withstand the rigors of their intended application.

Attention to Detail and Customer Care

Understanding the importance of surface finish and corrosion resistance, we applied a protective layer of rust-preventive oil to the RTJ weld neck flanges. This additional step not only enhances their shelf life but also ensures they arrive in pristine condition, ready for installation.
